But **FastAPI** will know that it has to solve `query_extractor` first, to pass the results of that to `query_or_cookie_extractor` while calling it.

次の章では、関数以外の「もの」が依存関係として使用できるものを見ていきます。

///

新しいリクエストが到着するたびに、**FastAPI** が以下のような処理を行います:

* 依存関係（"dependable"）関数を正しいパラメータで呼び出します。
* 関数の結果を取得します。
* *path operation関数*のパラメータにその結果を代入してください。
